The only thing you need is the system.ads file. The rest you don't need
and won't really be able to use for OS level programming.

Another feature you *will* require is the use of "pragma
Restrictions(No_Elaboration_Code);" to force the compiler not to generate
things like functions for arrays, i.e. conversion functions for indexing.

Also, use the -gnatdg switch to see what GNAT is generating and you'll see
what I mean.

As I remember it, GNORT doesn't exist anymore.

I also created a gnat.adc file with the following inside it:

pragma No_Run_Time;
pragma Restrictions(No_Exceptions);

That should be all you need.
